Dear Karl,
Search enginges are good for a lot of things, but they're limited when it comes to looking for books. However, if I pop over to
WorldCat, do a search on "su: obsessive compulsive disorter," then limit the results to "fiction" and "juvenile" I get 14 books, 6 of which have female protagonists. Here they are:
Kissing doorknobs / Terry Spencer Hesser.
Fourteen-year-old Tara describes how her increasingly strange compulsions begin to take over her life and affect her relationships with her family and friends.
Total constant order / Crissa-Jean Chappell.
Resentful and upset when her family moves from Vermont to Miami, Florida, and her parents' fighting escalates, high-schooler Fin develops OCD (Obsessive-Compulsive Disorder) and becomes consumed with numbers, counting, irrational worrying, and avoiding germs.
Multiple choice / Janet Tashjian.
Monica, a fourteen-year-old perfectionist and word game expert, tries to break free from all of the suffocating rules in her life by creating a game for living called Multiple Choice.
Grace's show of strength / Alexandra Moss.
In the last weeks of their first year at the Royal Ballet School, as they face exams and extra rehearsals for an end-of-year performance at the Royal Opera House, Ellie becomes very concerned about Grace's odd behavior.
Like a thorn / Clara Vidal
Throughout her childhood, Melie believes her mother is two people--Rosy Mother and Dark Mother--and she performs more and more rituals to keep Dark Mother away as she reaches adolescence, when she begins to realize that her mother is mentally ill and that Melie may be, as well.
Prey / Stefan Petrucha.
Sixteen-year-old Chelsea's obsessive-compulsive disorder (OCD) causes her to believe she must continually count objects to prevent awful things from happening, but when she agrees to pet-sit her biology teacher's six-foot monitor lizard, counting may not be enough.
If none of these is the right book or if the book wasn't children's / young adult fiction, write back in with anything else you can remember, and I'll give it another shot.
